Application, filed December 31, 1924. Serial No. 759,201.

`This invention relates to lasts of that type whieli are dividedtransversely thereby to torno e :tore part and a: heel port and in whichthe heel part inoifahly connected to the `tore part to facilitate theplacing; the last into a Shoe audits removal therefrom.

One familiar type ot divided laat is that which is known to the tredegenerally as a liiiigetl laet. liioneha oettheheel portanti the toe partare pivotally connected together so ae to permit the heel part to swingnn WardlgiT when the laet is to he removed fronti the shoe.

Another type oil` divided .last ie illuetrated in my Partout No.1.490.091, dated June 3rd, 'illt Thin :torni o? lost ie divided trauevereely `in two places to :torni the toe part, the heel part and anintermediate Wedgeshaped part which ifnovahle tranevereely ot' the lastand tlielheelipart ond toe part are connected hy e connecting; niemherwhich permits thein lreely to `niove bodily toward and troni eaeh otherin the direction ot the length of the laet.

rllhe hinged last has the advantage that when it ie nnloeled the heelpart can he swungupwardly ontot the ehoe which tends to 'liaeilitote theremoval ol the last from the Shoe, but it has the disadvantage that inthe upward swinging nilorement oit the heel. part the latter here a.sliding; motion over the oonnl'er of the shoe and. therefore, in orderto So'ingglhe heel part ol? the last lfipwardly soli lieient tort-enlnet he employed to overeome the lrietion ol' the counter against theheel part. llihen a` shoe is laeted the leather ie drawn tightlyT aboutthe last which. increases the l'rietional engagement hetween the lastand the counter portion ol the Shoe lend necessitates the applieationolf considerable torre to onlinr the heel part oit tlirelzletnpivardljy. lt sometimes?, happens that the rietional engagement betweenthe heel part ot the lat-it and the eonnter portion of the Shoe is euchthat in hretiltingv the hinged last the shoe ie liahlo to he damaged.

In order to give an nnderstnnding of the invention I have illustrated inthe drawings a Selected embodiment thereof' Whieh will now he describedalter which the novel fea tores will he lpoii'ited out in the appendedClaims.

Fin'. ffl is a Eet-tion on the line Irl-l, Fig. 2.

lillT inrijn'oved hiet is divided so as to 'forni the loro hart l. andthe heel part and an intermediate part l which is Shown ne Wider at thetop than at the lfmottoin. The heel part and loro part are connected hya conneetirnt meniher which pei-nnte them to more bodily toward andlroin eachother and also permite the heel part to have a Swingingmovement.

In the ijne'iferred i'orin ol my intention this eooneiftiiigg; ineinheris in the torni of a. toleeeopie nien'iliior eoinprieihg; the twoSeetionf Ll- :ind that have a teleeeopie relation. The eeetion il ieShown in the 'torni of a har or arm which "teint-ermee into theinen'iher li, the i latter heilig tnhlilar in shape.A

The telescopio menthol' 5 in shown arthrite inn' o idol' tli-:rteiifliiltg' onti'itndinally there of in which operation a pin orprojection 9 extonfilinn; troni the erin l0, this pin and sloteer/'ring' to limit the teleeeoping movement of the Connecting nieinher.

This; connecting; meinher ie jore'ferahly riidl oeenred to either the`:tol u "art t the ir im) struction shown the rigid connection is betweenthe telescopic member and the fore part of the last and the pivotalconnection is between said member and the heel part of the last. Themember 4 is shown as having a head 6 lwhich sets Within a groove or kerfformed in the fore part 1 and which is rigidly anchored in place byrivets or pins 7 thus rigidly securing the arm 4 to the fore part l.

The heel part 2 is shown as pivotally connected to the telescopicsection 5 by means .of a suitable pivot pin 10, said` heel part beingformed with a kerf or recess 20 in which the end of the telescopicsection 5 is received.` I

The intermediate` section 3 is shown as having acentral opening 11extending therethrough in which thetelescopic member is received.Theopening 11 in the sect-ion 3 hasi'sutlicient dimension transverselyofthe last to permit'said member 3 to move vertically fromthe operativelengthened position shown in Fig. 1l to the position shown in Fig. 2.With thisfeonstruction the intermediate section 3 is permanentlyconnected'to the other parts of the last or is non-detachable therefromand has a limited movement'transversely of the last.

'When the last is in use the intermediate section is in its operativeposition shown in Figpland the telescopic connection is fully extended,the pin 9 bearing against the lefthand end of the slot 8. The last islocked in this position by means similar to that shown in my Patent No.1,496,091,

Vdated June Y3, 1924, and which comprises a springppressed locking pin12 carried by the intermediate member 3 and adapted to engage an'opening'13 in a plate 14 Vthat is secured to the front face of the heel section2;

When the last'i's thus in its lengthened positionthe faces of theintermediate section Sbear firmlyV against the faces of the toesectionand heel section and since the 'intermediate section is locked inthis position by the lockingv pin 12 the resultant last structure willbe one which is amply rigid to withstand any pressures to which the lastmay besubjected in the making of a shoe.

p Asa further means of stiifening the last and enabling it to withstandthe heavy pressure of such machines as levelling machines, sole layingAmachines and similar machines I provide means for locking theintermediate member 3 to the fore part of the last thus obviatingv anypossibility of the last opening'at the joint between the fore part andintermediate part. The intermediate part. 3 hasy ay pin 21 extendingtransversely therethrough v'which is adapted to engage inlaJ notch 22VAformed in the upper face of the arm 4 when the last is in extendedposition as shown in Fig. 1., This pin and knotch serve to tie theintermediate part Il and fore part together and prevents their giving oryielding away from each other when a heavy pressure is applied to thebot- .Fig 2 thus allowing the lufel part of the last to il'reely movebodily forwardly with the result that the last .is positively shortened.

e In fact, with the construction shown the shortening of the last may bea very considerable amount as indicated by the two dotted line positionsshown in Fig. rIhis positive shortening of the last removes all thestrain on the shoe to which it was subjected by the last when in fullyextended condition and the last is then simply lying in the shoe in aloose manner with the heel part separated from the counter 4 of thcshoe. The last may then be removed from the shoe by swinging the heelpart upwardly as shown in Fig. 2, the amount of swinn'- ing rn'ioveinentof which the heel is capab o being determined somewhat by the amount towhich the last is shortened. Since, however, the last is simply looselylying in the shoe and not under any strain the amount which the heelswings relative to the shortening of the last will depend somewhat uponthe nature of the shoe. The removal of the last is made easy because itis Jositively shortened and all strain is taken rom it before the heelpart is swung upwardly. As is well known a last is usually much wider atthe bottom ot the heel portion than at the top thereof, especially in awomans shoe, and, therefore, in the operation of removing a last fromthe shoe the wider portion of the last at the bottom ot the heel has tobe withdrawn through the, narrower opening at the top of the shoe. Alast which has the capability olt shortening longitudinallyimlepemlently ol the swinging movement ot the heel part is much easierto remove from a shoe having a narrow opening at the top of thc heelthan a last in which the heel has a swinging move,- ment only. Y

Furthermore, my improved last is olf special advantage in the relastingoperation involved in the manufacture of turned shoes. eczuse of thefact that; the last.v can slierten positively a very considerable amountit is very easy to insert it into the shoe for the re-lasting operationafter the shoe has been turned and this can `be done without distortingor injuring the shoe in any way. Vhen the last has been thus insertedthe forcing of the intermediate member 3 into loo los

its operative position simply lengthens the last longitudinally and thusstretches the upper over the last Without any slipping movement ot theheel part of the last on the counter portion of the shoe such as isinvolved in swinging the heel part doivnivardly into the shoeu rlhslocking pin l2 can be released in various Ways and I have herein shownfor this purpose a releasing member l5 which can be moved 'forwardlythereby to release the locking pin by means of a suitable implement:inserted through the opening 16 in the Wall of the usual thimble 17lthat is located in the heel part.

I claim:

l. A last having a lore part, a heel part, and a telescopic memberpermanently con necting said parts and operating to limit the movementet said parts away trom each other, said telescopic member comprisingtivo sections having a telescopic relation, one section being rigidlysecured to the tore part oit the last, and the other section beingpivotally secured to the heel part, whereby said last may be shortenedeither by moving the heel. part toward the fore part as tar as thestructure will permit, or by partially conn tracting the telescopicsection and then swinging the heel part about its pivot.

2, A last comprising a :fore part, a heel part, an intermediatewedgeshaped part eze `tending 'from the top to t-he bottom ot' the lastand having a limited movement transversely thereof, a telescopic memberIpermanently connectingl the heel part and the llore partand whichpermits them to move freely' toward and trom each other in the directionof the length ot' the last, thereby to lengthen and slierten the last,said telescopic member being constructed to limit the movement ot theheel part and. toe part away from each other, said interniediate partwhen in operative position holding the last,- lengthened to the extentpermitted by the telescopic men'iber, and the heel part being pivoted tosaid telescopic member, whereby the last may be shortened after theWedge- .shaped part has been moved transversely ot the last either bymoving the heel part toiiard the tore part in the direction ot thelength of the last as tar as permitted by said Wedge-shaped part or bygiving the heel part a slight movement toward the 'fore part and thenswinging the heel part about its pivotu 3. A last comprising a torepart, a heel part, an intermediate ivedgeshaped part having a limitedmovement transversely ot the last, a telescopic member permanentlyconnecting the heel part and fore part and which permits them freely tomove toward and from each other in the direction of the length oit thelast but limits the extending n'iovement, one et said parts beingpivoted to said telescopic connection, and means te loelt the last inextended relation.

A last. having a iore part, a heel part and a telescopic memberpermanently con necting said parts, said member comprising tivo sectionshaving a telescopic relation, one section being rigidly' secured to onepart el the last and the other section being pivotally secured to theother part ol' the last.

5. A last having a tore part, a heel part and a telescopic memberpermanently conn necting said parts, said member comprisu ing twonoirseparable sections having a telescopic relation, one section beingrigidly secured to the tore part of the last and the other section beingpivotally secured te the heel part of the last.

6. A last comprising a tore part, a heel part, a Wedge-shapedintermediate part mov able transversely ot the last, a telescopic memberhaving tivo non-separable sections, one section thereo't rigidly secured`to the toe part ol the last and the other section piv otally secured tothe heel part of the last, and means lor locking the intermediate partto the tiret-named section ot said telescopic member,

7. A last comprising a tore part, a heel part and a wedge-shapedintermediate part, a telescopic member connecting said parts andconiprising an arm rigid with the 'fore part and projecting toward theheel part and a co-operating member pivotally secured to the heel partwith which .said arm telescopes, said. arm having a notch, and a pincarried by the intermediate part and adapted to engage said notch whenthe last is in its lengthened condition.

S. A last connirising a 'fore part, a heel part, a Wedge-shapedintermediate part extending trem the top to the bottom of the last, atelescopic member permanently connecting the heel part and tore part andpermitting them to move freely toward and from each other .in thedirection et the length of the last thereby to lengthen and slierten thelast, said telescopic member en tending through an opening in theintermediate part. ivlicreby said intern'iediate part is non-detachablefrom the other parts and has a limited moven'ient transversely oil thelast, one section ot the telescopic member being rigidly secured to the'tore part of the last and the other section being pivotally secured tothe heel part et the last.

In testimony whereof, l have signed my name to this specification.
